Pure Kraft 45 Degrees Linear Leg Press

Manufacturer load specs

Mechanical model Partial model

F = SR + P·sin(45°) ± friction → plate part known (0.707·P), SR unknown

1 input(s) sourced · 2 to measure on site · explicit assumption on the band of: θ

To measure: SR (Starting resistance (empty sled)) · μ (Friction coefficient)

Starting resistance missing, so absolute values cannot be given; only the plate part of the force (P·sin θ, with its angle band) is computed – see the table in the derivation.
